Rock Science vs Rocket Science: The Importance and Advantages of a Petroleum Engineering Education
Petroleum engineering is a unique discipline. When you examine a typical petroleum engineering curriculum, you will find an array of courses not only intended to train and educate one as a petroleum engineer, but also as an all-purpose engineer. A petroleum engineering graduate, in many instances, holds some of the knowledge of a chemical engineer, a mechanical engineer, a civil engineer, an electrical engineer, and especially of a geologist. Therefore, it is not surprising that many think of a petroleum engineer as a jack-of-all-trades.
The petroleum engineer is typically the common denominator in oil and gas projects, providing the design specifications and applying the end product. The problem for most engineers without the petroleum engineering education is that they lack the geosciences background needed to make best use of the advanced technologies for petroleum E&P. Every engineering discipline sets claim to a mother science. Geology is considered the mother science of petroleum engineering, as chemistry is for chemical engineering.
One of the major factors that sets the petroleum engineer apart from other engineers is the vast amount of imagination and creativity so intertwined with petroleum E&P. As economist and author Lester Thurow put it, “The oil industry still produces oil, but it has been infused by so many new technologies that it should be thought of as one of the new manmade, brainpower industries like biotechnology.”
Traditionally, rocket science has been the point of reference for sophisticated science and technology. I argue that petroleum engineering is as sophisticated, if not more so, than rocket science. Petroleum engineering is also rooted in imagination and dealing with unknowns, except that as rocket scientists venture into the space above, the petroleum engineers venture into the earth below to unlock the mysteries of the porous media. The subsurface formations hold numerous peculiarities that are only deciphered by integrating basic science and high-level technology—work done by creative and clever petroleum engineers.
It is a pointless and futile exercise to concern yourself with oil prices as you start your career and progress several years into it. Even the so-called experts do not know what prices are going to be. Look at the events of the last several months, if one needs proof. Furthermore, to complicate the matter, we do not even know how much oil and gas is left in the world to produce. Even if we did, we still could not account for what will be discovered in the future. The petroleum era, marking the period in which oil and gas has contributed significantly to society, is 125 years old by conservative estimate. And by all conservative predictions (which we have already dismissed), it should last for another 50 years, on the basis of current reserves estimates. Adding the two, one could define an era comprising 175 years of sustained petroleum production.
This “crude” analysis encompasses 5,000 gigatons of fossil fuels. However, there will be a new player in the near future: gas hydrates. The current known deposits of gas hydrates are 10,000 gigatons. The technology is now limited for the production of gas hydrates, but as the technology advances, gas hydrates will be produced. And when that begins to happen, guess who will be most responsible for the exploration and production of gas hydrates? If you guessed petroleum engineers, you would be right. If we assume the current world petroleum consumption, the current known levels of gas hydrates will last us another 350 years. That would call for another eight generations of petroleum engineers to guide the production of carbon-based energy. Thus, we have a well-founded argument by which we should dismiss any notion that petroleum is a “sunset” industry.
The petroleum engineering discipline and the petroleum industry are synonymous in a way unlike any other such pairing of engineers and an industry. Therefore, the petroleum industry has an unusual amount to say about the education and training of petroleum engineers. The industry’s role in this is widely and enthusiastically embraced by the academic community. The infusion of ideas and mentoring by the petroleum-industry professionals into the education and training of new petroleum engineers is an important ingredient of the future of petroleum engineering.

What discipline, what profession offers you the opportunity, and the challenge, to work for the common good in a way comparable to petroleum engineering? Where can a professional 22 or 23 years old be in charge of millions of dollars of assets, have the vast responsibility to care for the health and safety of many, be responsive to the sensitivity of our environment, and make a profound, positive impact on the lives and the quality of life of millions? In many ways, petroleum engineers are world citizens in the work they do and the way they work.
In my years in the industry and in academia, I have frequently observed the dilemmas that young graduates face as they enter the workforce. One question they debate is what type of company they should start with, an E&P company or a service company? Earlier in this article, I pointed out the importance of a strong petroleum engineering curriculum and the role of high-level technology in the petroleum industry. My advice to engineers entering the industry has been constant over the years. I believe the name of the game for young professionals is the accumulation of knowledge and experience. As long as you can gain technical know-how, it does not matter what type of company you work for.
Entry-level petroleum engineers must develop the skills to apply to the conditions and environment in the field. For decades, lasting into the 1980s, there was a belief that you would gain more technical skills from E&P rather than service companies. This may have been true, when the E&P companies were handling nearly all the technical and operational designs and executions of the jobs. The service companies were there to supply the equipment and the personnel that operated the equipment. The events of the mid-1980s, with the drop in oil prices, changed the role of the service companies. The downsizing of E&P companies created a vacuum that was enthusiastically picked up by the service companies. The service companies became more actively involved in the design and implementation of the operations themselves. We now see that many service-company engineers are actually housed within the E&P companies to oversee the daily operations. The E&P companies are now highly dependent upon service companies to design and execute the jobs for them.
Many of the best practitioners of any technical area in the oilfield are now in the service sector. Therefore, my point should now be clear that as long as you can learn and gain the experiences that you lack, there is no major reason why you should choose one type of company over another. Of course, many look at additional factors to supplement their decision, such as financial incentives and benefits. My advice is that the technical gain from a job offer is the most critical, and if all is equal, then one can look at nontechnical factors to make a job-acceptance decision.
The other question that young petroleum engineers so often debate, usually after a few years on the job, is whether to choose a technical or a management ladder to advance in their careers. My advice has been constant here, as well. I believe a manager cannot perform well without solid technical credentials. I believe a mediocre technical person can never be a good manager. (I and perhaps you have come across many managers who lack good technical foundation.) That is the reason I have emphasized good. Being a good and a competent manager can be a rewarding career for the individual and the company. We desperately need such managers in this industry. So, if you hold solid technical capabilities and have developed the soft skills and acumen for leadership, then you would be a good candidate for a management position, if that is the direction you wish to take.
In conclusion, petroleum is a high-tech industry that needs talented professionals and experienced individuals who can mentor the younger professionals coming in and moving upward. It needs innovative technology, capital, and skillful collaboration, and it needs to foster and implement socially responsible development. Why are all these needs so important? Because the industry is going to be around for many generations.
